  3. Understanding HTTP Status codes If you are a non-techie and don’t know exactly what are HTTP status codes, they can be understood as a set of standardized three-digit numbers used by web servers to communicate the outcome of a client’s request. This means they provide you with the status or information about the success redirection, type of errors, and other states of the request-response cycle. These status codes play a crucial role in web communication as they provide important feedback, indicating whether a request was successful or encountered any problems. With the assistance of these codes, one can readily take appropriate actions based on the response received from the server.

  4. What causes 401 Error? Missing or invalid credentials: If you are unable to provide authentic credentials due to any reasons or provide incurred or expired credentials, a 401 error will be triggered. Unauthorized access attempt: When you try to access a resource that requires authentication, but the provided credentials do not grant sufficient permission, a 401 Error will be returned. Revoked or Expired tokens: If you use an expired or outdated authentication token, the server may respond with a 401 error. Corrupt or outdated Browser cache and cookies: If you ever see a 401 error, it’s usually because your browser’s cache and cookies are outdated or corrupted. This can cause trouble with authorization. If your browser doesn’t have the correct authentication credentials (or any at all), the server won’t accept your request. Just remember to keep your browser’s cache and cookies up to date to avoid running into these kinds of errors. ● ● ● ●

  5. Incorrect or Outdated URL: Sometimes, in a rush, you might mistakenly enter the wrong URL or encounter a situation where the URL has been changed. This can trigger a 401 error as a result. Plugin conflicts: Sometimes, a 401 error can happen because of a plugin issue. For example, if you are using a firewall or security plugin that might mistakenly think your login attempt is suspicious and block access with a 401 error to keep the page safe. ● ●
